Title:
WASTEWATER TREATMENT EQUIPMENT AND METHOD OF WASTEWATER TREATMENT
Document Type and Number:
WIPO Patent Application WO/2006/092920
Kind Code:
A1
Abstract:
A wastewater treatment equipment in which by the use of surfactant tank (9) and surfactant pump (8) constituting a surfactant adding section, a surfactant is charged in micronanobubble reaction vessel (3). Consequently, in the micronanobubble reaction vessel (3), micronanobubble producing machine (4) can produce micronanobubbles stably in high efficiency using a treatment object water containing the surfactant as a raw water. Therefore, not only can any wastewater having been introduced in the micronanobubble reaction vessel be efficiently pretreated by micronanobubbles to thereby attain an enhancement of wastewater treatment efficiency but also the treatment load on wastewater treatment equipment (14) as the step subsequent to the pretreatment can be reduced to thereby enable reduction of the scale of the wastewater treatment equipment (14).
